Whitney Houston's Medical Records Sought by Investigators

Confirming to PEOPLE that “prescription medication was recovered from the scene” of where Houston, 48, was found unresponsive in her Beverly Hilton hotel room, L.A. Coroner Asst. Chief Ed Winter says, “We are trying to locate some of her doctors to get all possible medical records.”

Winter declined to comment on what drugs were found in Houston’s room, but he does say investigating the records “is normal procedure for us.”

Asked if the case appears to be similar to the Dr. Conrad Murray investigation, he says, “It doesn’t appear so.”

Murray was convicted of involuntary manslaughter in Michael Jackson’s death.
